Samsung Refrigerator Water Filter Guide (DA29-00020B & More)
Samsung refrigerators use a small number of filter families, and picking the right one is just matching the DA29 or HAF part number on your old filter. Swap it every six months for clean water and steady ice.
Which Samsung Filter Do I Need?
Most modern Samsung French-door and side-by-side fridges use the DA29-00020B (also called HAF-CIN / HAF-CIN/EXP) — the round twist-in filter inside the fridge. Older models use the DA29-00003G (Aqua-Pure Plus). Newer (roughly 2017+) 4-door Flex and Family Hub-era models use the HAF-QIN (DA97-17376B). Match the exact part number printed on your current filter or in the manual — Samsung filters look similar but are not interchangeable.
OEM vs Compatible Filters
Genuine Samsung filters run about $40-50. NSF 42/53-certified aftermarket compatibles cost roughly $15-25 and are a reasonable swap — the NSF mark confirms they actually reduce chlorine taste/odor and contaminants. Samsung filters in particular are a popular target for cheap uncertified copies that fit loosely or leak, so stick to certified ones.
Replace Every 6 Months and Reset
Change the filter every six months or when flow drops. Most Samsung filters twist a quarter turn to remove and install — no tools. After replacing, run about 2-4 gallons through the dispenser to clear air and carbon dust (early sputtering is normal), then reset the indicator by holding the 'Ice/Water' or 'Filter' button (often 3 seconds) until the light returns to its normal color.

FAQ
Most use the DA29-00020B (HAF-CIN). Older models use DA29-00003G, and some newer in-door models use HAF-QIN. Match the part number on your current filter or in the manual.
Samsung filters look alike but differ by model. The reliable method is to read the DA29 or HAF number off the old filter rather than guessing by fridge model year.
Yes, as long as it is NSF 42/53 certified. Certified compatibles cost about half the OEM price; avoid uncertified copies, which are common for Samsung and can leak.
